Wurth Black Super RTV Silicone is a High-grade adhesive and sealing compound for use with motor vehicles.
-Very good resistance to chemicals - suitable for use in critical areas in which the seal may temporarily be in contact with several fluids. This product shows an excellent resistance against motor and gear oils, refrigerants and anti-freeze.
- Acid-free hardening system - non-corrosive and non-conductive, therefore no negative effects on electronic components or Lambda sensors.
- High temperature stability - utilization in the temperature range on machinery and engines possible.
- Sealant in a compressed air spray can - easy dosage without auxiliary devices. Optimum handling, which means that an even product application using the beads is possible.
Optimal adhesion is achieved on clean and dry surfaces. Old sealing materials must be removed completely from the sealing surface.
